As long as they kept whatever process to build them in line with previous revisions, I'd bet there is still a way into their service mode without opening the unit up to access the battery.
Of course, as stated previously, no one ever mentioned to the 'boss' who runs his yap nor half the folks who have made or used a pandora battery that the magic isn't really in the battery, it's in service depos getting $75+ to do a 5 min job correcting something that a customer should be able to correct without hacks anyway.
